Ready Mixed Concrete01:26

Ready Mixed Concrete

373
Ready-mixed concrete, also known as pre-mixed concrete, is prepared in a centralized plant and then transported in trucks to construction sites where it is ready for placement. This type of concrete is categorized into central-mixed, truck-mixed (or transit-mixed), and shrink-mixed. Central-mixed concrete is entirely prepared at a plant and moved to the site in agitator trucks that rotate at a speed of 2 to 6 rpm. Truck-mixed concrete, on the other hand, has the ingredients batched at the plant...

What is a Hypothesis?01:14

What is a Hypothesis?

15.0K
A hypothesis can be a simple sentence or statement about a property or any phenomenon observed or predicted for a population. It is usually a claim about a  property of the population. It can be stated for any field observations or experiments. A hypothesis statement cannot be said to be right or wrong as it is merely a statement. It needs to be tested through an elaborate data collection process and an appropriate statistical test. A hypothesis should be a general but not a vague...

Types of Hypothesis Testing01:11

Types of Hypothesis Testing

27.9K
There are three types of hypothesis tests: right-tailed, left-tailed, and two-tailed.
When the null and alternative hypotheses are stated, it is observed that the null hypothesis is a neutral statement against which the alternative hypothesis is tested. The alternative hypothesis is a claim that instead has a certain direction. If the null hypothesis claims that p = 0.5, the alternative hypothesis would be an opposing statement to this and can be put either p > 0.5, p < 0.5, or p...

Errors In Hypothesis Tests

6.0K
When performing a hypothesis test, there are four possible outcomes depending on the actual truth (or falseness) of the null hypothesis and the decision to reject or not.

Hypothesis Test for Test of Independence01:16

Hypothesis Test for Test of Independence

8.2K
The test of independence is a chi-square-based test used to determine whether two variables or factors are independent or dependent. This hypothesis test is used to examine the independence of the variables. One can construct two qualitative survey questions or experiments based on the variables in a contingency table. The goal is to see if the two variables are unrelated (independent) or related (dependent). The null and alternative hypotheses for this test are:
H0: The two variables (factors)...

Statistical Hypothesis Testing01:16

Statistical Hypothesis Testing

7.0K
Hypothesis testing is a critical statistical procedure facilitating informed, evidence-based decisions. It begins with a hypothesis, which is a tentative explanation, or a prediction about a population parameter. This hypothesis can be either a null hypothesis (H0), indicating no effect or difference, or an alternative hypothesis (Ha), suggesting an effect or difference.
Statistical significance measures the probability that an observed result occurred by chance. If this probability, known as...

Area of Science:

  • Microbiology
  • Bioinformatics
  • Genomics

Background:

  • Hypothesis-driven research is vital but requires a robust framework of aggregated scientific knowledge.
  • This essential framework is currently underdeveloped in microbiome studies.
  • Meaningful scientific questions in microbiome research necessitate this foundational knowledge base.

Purpose of the Study:

  • To highlight the need for non-hypothesis-driven research in microbiome studies.
  • To demonstrate how discovery-driven, tool-driven, and standards-driven projects can build a knowledge framework.
  • To advocate for community investment in research infrastructure for microbiome science.

Main Methods:

  • Utilizing examples from laboratory projects: spatial mapping, the American Gut Project, and the Earth Microbiome Project.
  • Showcasing knowledgebase-driven tools such as the Global Natural Products Social Molecular Networking (GNPS) and Qiita.
  • Integrating various hypothesis-driven projects under the umbrella of the Earth Microbiome Project.

Main Results:

  • Non-hypothesis-driven projects are essential for creating a collective knowledge framework in microbiome research.
  • Spatial mapping, large-scale citizen science (American Gut Project), and comprehensive environmental sampling (Earth Microbiome Project) contribute to this framework.
  • Computational tools like GNPS and Qiita facilitate data integration and knowledge discovery.

Conclusions:

  • Investing in community resources for infrastructure, controls, and standards is critical for microbiome research.
  • Such investments will significantly amplify the impact of hypothesis-driven research programs.
  • A collaborative, infrastructure-focused approach is key to unlocking the full potential of microbiome science.
